<P>I'm sorry I made a mistake the subnet between catalyst4006 and customer's firewall is</P>
<P><FONT color=#ff0000>10.10.1.213/30, Catalyst4006's interface address is 10.10.1.213, firewall's interface <BR>
</FONT>address is 10.10.1.214. <BR>

<BR>
Sorry.<BR>

<FONT color=red>> Is that the firewall interface is 10.10.1.122, or is it 10.10.1.124?</FONT><BR>
<FONT color=red>> 10.10.1.122 is a host address in the 10.10.1.120/30 subnet.</FONT><BR>
<FONT color=red>> 10.10.1.124 is a /30 network. Either way, you're dealing with two</FONT><BR>

<BR>
On top of that, we have this discrepancy:<BR>

<BR>
So the router's address isn't even on the same subnet as the firewall's. <BR>
Again, it's not clear how it ever worked.<BR>
